I have a deep dish NRG, it seems pretty decent for the price. I actually laid it on the floor, stepped on it with some weight (not full body weight) and it didn't collapse. I'd think you'd damage the quick disconnect before twisting it in half.

I had a deep dish NRG in my Honda civic. The top portion of the wheel (the part that isn't supported by any spokes) bent/broke. My friend bought the same one for his Civic, and it did the same thing. Cheap junk. Buy a Momo or a Sparco.

Keep an eye out on ClubRoadster (if you can monitor it without bursting in to a flaming ball of combustion and rage) and you can find quality wheels for ~$125. I have a 330mm Sparco Ring, 350mm Momo F-1 and 350mm Mazdaspeed. I bought all of them used.

Do you guys think urban trash walking by my shitbox in the middle of the night would be interested by the lack of a steering wheel, or a deterrent?

Interesting question. I would say if they are looking to boost a car, it's an obvious deterrent. Assuming there's nothing of value in the vehicle worth stealing, nothing appealing in the cabin from external view, I'd say overall it's a deterrent.
